NJW4190 Doubler Charge Pump IC GENERAL DESCRIPTION PACKAGE OUTLINE The NJW4190 is the doubler charge pump IC that operates wide 5V to 17V input range. With only the external part of an input/output capacitor and a charge pump capacitor, can compose the doubler voltage circuit. It has a high current capability and a corresponding to small-sized capacitor compared with conventional product such as popular 7660/7662. For usability, it has ON/OFF function, Output Voltage Adjustable function and external synchronous function. The NJW4190 is suitable for the bias voltage of CCD, sensors and operational amplifiers. There is the NJW4191 for inverter voltage output application. NJW4190R NJW4190M FEATURES Doubler Output 34V max. Wide Operating Voltage Range 5V to 17V Maximum Output Current 55mA max. Correspond to Ceramic Capacitor (MLCC) VOUT Programmable ON/OFF Function Built-in Oscillation Circuit 300kHz typ. External Synchronization Function divide-by-4 counter (A ver.)
